To all whom it may concern:

Be it known that 1, MAX A. Ronssre, of the city of Omaha, county of Douglas, and State of Nebraska, have invented a new and useful Composition for Treating Convas and other Fabrics, which is described in the following specification.

My said composition is primarily designed to be applied to cotton fabrics for the double purpose of rendering the same bothwaterproof and noninflammable-in other words, impervious to water and diflicult of ignition and of combustion.

The ingredients of the com osition are as follows, and are mixed pre erably in the manner, and approximately in the proportions, following, viz.:

(1) Melted paraflin wax, to be mixed while in liquid form, one pound.

(2) Paraffin oil, to be mixed with said melted paraflin wax, three pints.

(3-) Fish oil or cottonseed oil, preferably the former, to be mixed, apart from the mixed paraffin oil and paraflin wax, with the two ingredients next to be named, one quart.

(4) Burnt umber or other dry earth color, round exceedingly fine and mixed, apart from said paraflin oil and wax,

the ingredient (5) which is next to be mentioned, one half pound. ter, however, maybe altogether omitted from the compound, if no coloring is desired.

(5) Gasolene, last specified in redients (3) and (4), apart. from said paraflln oil and wax, and then, together with those specified ingredients, mixed with said mixed paraflin oil and wax, three halfpints. I (6) Burnt alum, the anhydrous aluminum and potassium sulfate, added to the foregoing ingredients, and mixed in, four ounces.

(7) Common salt, added to the foregoing and mixed in, four ounces.

The resulting product is of pasty consistency, not fitfor use, but convenientfor transwith the last mentioned ingredient (3) and with V value, This coloring matfirst mixed with the two portation and storage, and capable of be- 1ng kept in storage for years without deterioration.

(8) Gasolene, added to the foregoing pasty mixture just before using, two quarts.

To this mixture no water should be admitted, and no drier which can harden.

The composition is specially designed for tents, tarpaulins, hay covers, wagon covers, horse covers, and other forms of canvas or cotton fabric. When applied to one side of the fabric with a brush, like paint, it renders the fabric pliable at all temperatures, and incapable of ready ignition or combustion. It obviates all need of drying the fabric, after use or wetting and before folding up and laying away; and prevents hardening, cracking, rotting, molding and burning.

The reason for using paraffin oil for mix ing with the melted paraflin wax, as described, lies in the special availability of that oil for mixing with that wax. The fish oil,-

or cottonseed oil as its substitute, is chosen because it is cheap, stays always soft, has considerable preservative effect, and retains its properties without having been refined; linseed oil would injure the fabric, and other oils would gum. The alum and common salt are selected for their fire-proofing and are used as ingredients of the composition for the purpose of diminishing the combustibility of the material to'which itis applied.

I am aware that parafiin wax, paraflin oil, gasolene or petroleum oils, alum, have been used in waterproofing compounds; but am not aware that all the ingreclients of my composition have been used together, nor in similar proportions, nor for the same waterproofing and fireproofing purposes.

I claim as my invention-- 1. The herein described composition of flin 90 matter, consisting of paraflin wax, para oil, fish oil, ground color, asolene, .burnt alum and common salt, all mixed together.
